In OEMCrypto v16, we dropped support for 'cens' and 'cbc1'. However, we
did not redefine the pattern (0,0) to be a valid pattern for 'cbcs', even
though it was no longer being used to signal 'cbc1'. Instead, we made
the CDM reject CTR with a pattern ('cens') and CBC with a (0,0) pattern
('cbc1') to mirror the behavior of OEMCrypto v16.
However, some apps have been using 'cbc1' mode to decrypt audio in
'cbcs' content. This is normally not possible but is possible for a
subset of content. Furthermore, it is easy to do by accident because of
the way most packagers package 'cbcs' audio and the special significance
Widevine has historically given the (0,0) pattern.
This patch updates the CDM to not reject CBC with a (0,0) pattern but
instead treat it as 'cbcs' content. To decrypt it correctly, the pattern
is treated specially inside the CDM core and converted to the
recommended equivalent pattern — (10,0) — before passing the content to
OEMCrypto.

This implements the CDM code changes necessary to take advantage of
Combined Decrypt Calls on OEMCrypto v16. The result of this is that
WVCryptoPlugin is much lighter now because it can pass the full sample
down to the core in one call, but CryptoSession is heavier, as it now
has to handle more complex fallback logic when devices can't handle
multiple subsamples at once.
This patch also removes support for the 'cens' and 'cbc1' schema, which
are being dropped in OEMCrypto v16. This fixes an overflow in the code
for handling those schemas by removing it entirely.
This patch also fixes the "in chunks" legacy decrypt path to use larger
chunk sizes on devices with higher resource rating tiers.

This cleans up some warnings in the Android glue code:
1) Checking if unsigned values are >= 0.
2) Using {0} initializer syntax instead of fully expanding to {0,0}.
